Plantains should always be weed free, weed control starts during the field preparation and weeds are initially controlled about every 6 to 8 weeks but when the plantain canopy closes, at about 5 to 6 months after planting, weed infestation declined due to shading.
Ensure that any plant with a superficial root system should be considered a weed and therefore must be eliminated. Grasses or herbs are the most pernicious weeds because they derive their nutrients from the same level of the soil as the plantains while tree seedlings are not considered to be weeds.
Weeds can be controlled through mulching, chemically or manual clearing. Mulching is the most efficient means because a mulch layer can impede or prevent weed growth. Chemical control is expensive and in some circumstances also dangerous to the plants.
Manual weeding is not recommended because although the weeds are thereby effectively controlled because of slashing or hoe weeding but it will inevitably damage the plantain root system therefore adequate care must be taken during manual weed control if it appears to be the only option you have to control weeds in your plantain farm.
